Re: turn-on-*-mode

[Richard Stallman]

    The only situation where the turn-on-*-mode functions are really needed
    is hooks:
       (add-hook 'text-mode-hook 'turn-on-auto-fill)
    is much better than
       (add-hook 'text-mode-hook (lambda () (auto-fill-mode 1)))

Right.  So my idea is, let's add such functions
for the modes people often want to enable in these hooks.
